Best option in 2023 for IOS photos backups?

I have a pi 4 4gb, and an external SSD.

What are my best options here?

Ideally it would be an automatic background backup, without having to open the app.

Bonus points if i could create an automatic backup to S3.

I took a look at nextcloudpi, and it seems to be close to what i want, but i was just wondering if theres something more lightweight since it has a lot of stuff i wont use, like calendars and contacts etc.

Thanks!
